The old native implementation of findAddress only accepted addresses
without zip codes if they appeared at the end of the string. This was
probably a bug as the documentation implies this should work in all
cases, but fixing this bug has caused a lot of false positives while not
fixing very many false negatives and this functionality is being
deprecated anyway, so change it back.
